== sanity-lfsck test 29b: LFSCK can repair bad nlink count (2) ======================================= 22:03:53 (1532469833)
#####
The object's nlink attribute is smaller than the object's known
name entries count. The LFSCK will repair the object's nlink
attribute to match the known name entries count
#####

Inject failure stub on MDT0 to simulate the case that foo's
nlink attribute is smaller than its name entries count.
